VoIP/SIP monitoring tasks create monitoring agents that connect to a specified VoIP server using the supplied credentials to ensure that the service is available.  To accomplish this, SIP Monitoring is provisioned as either an extension or a client on the VoIP system and configured to call a specific number using a specified SIP server with certain parameters. The expected result of the call is setup as “Answer”, “No Answer”, “Busy”, or an error condition (if there is an unexpected result).

If an error is detected, SIP Monitoring records all properties of the error, which helps to pinpoint where the error condition is occurring. SIP Monitoring reports these error properties as Blobs of text accessible in online reports:

SIP Final Response:408
SIP Final Response Description: Request Timeout
Media: False
TimedOut: True
